Hi All I am very new to the yorkie world as we just got our baby yesterday and travelled from Scotland to England for her she is only 6 weeks and adorable

and very small.The breeder assured me she was fully weaned from her mum on to solid food as the mum lost interest in the pups two weeks prior.
I brought her home and she did'nt eat or drink much last night , so today I started hand feeding her and syringing her with water, as she was lethargic I contacted my local vet and he told me to give her water and honey mixed together every 2 hours and keep feeding her by hand every two hours also.
This is very very worring, is there anything else I can do to help her.
She has been a bit more energetic this evening and has came out of her bed to play for 10 mins, so hopefully she is getting better.
I feel angry with the breeders as they should have known better as I know now that 6 weeks tommorow is far too young to be away from her mother and fammiliar surroundings.
Any information will be grat thanks.
